Patent EP-0253691-A2 (EP)
Inventor: LAWLER HARLAN
IPC: H01L23/488
Filed: 1987-06-11
Abstract: A process for bonding silicon die (10) to a package. This process comprises the following steps: (a) providing to the back surface of the die (12) an adhesion layer (14) of material which exhibits superior adhesion to both the silicon die and a subsequently applied barrier layer (16); (b) providing to the adhesion layer (14) a barrier layer (16) which is impervious to silicon; (c) providing to the barrier layer (16) a bonding layer (18); and (d) bonding the die to the package by activating a binder composition disposed at the interface of the package and the bonding layer. The barrier layer prevents the migration of silicon to the bonding layer, both at the time of application of the bonding layer to the die and at the time of bonding the die to the package. The adhesion layer enhances the adhesion of the barrier layer material to the back surface of the die. Titanium is the preferred adhesion layer material while tungsten is the preferred barrier layer material. The bonding layer preferably comprises gold while the preferred binder composition is a gold-tin alloy solder. The enhanced adhesion of the barrier layer which prevents silicon migration into the gold produces highly reliable bonds. In another embodiment, a stress relief layer is interposed between the adhesion layer and the back of the silicon die. The material of the stress relief layer is alloyed to the silicon at the back surface of the die which relieves stresses in the die and enhances the planarity of the back surface. This produces bonds which exhibit superior electrical and thermal contact characteristics.

Abstract: A method for sorting rubbish using conveying devices in a conveying path via various sorting stations is improved to the effect of an early dividing up of the material stream and a thus more effective and easier handling of the branch streams in that the rubbish is subjected in a sorting station located in a front part of the conveying path to a suction air stream directed toward an air-permeable steep surface and thus partially adheres to the steep surface under a suction effect, and is partially collected below the steep surface and conveyed away. A rubbish sorting device for carrying out such a method is designed in such a way that the steep surface is connected at the rear to the suction side of a blower, a conveyor opening above the steep surface and a collecting and conveying-away device being arranged below the steep surface. In order to provide for the material to be detached at the steep surface to be constantly transported away, the said surface is preferably of movable construction. <IMAGE>

Abstract: A computer controlled digital imaging processing system is devised which operates to compose and construct a sequential stream of scenes for a 2-dimensional display from a library of images such as trees. The processing speed is sufficient to permit a real-time, or near real-time, analysis of the images by a human operator or a hardware/software equivalent thereof. The images of objects stored in the library are in rectangular form. 
     A vehicle simulator such as a helicopter simulator has a field of view which represents what is seen through the "windshield" thereof which in the simulator is the screen of a computer monitor. A perspective mapping process is provided for mapping images of objects which appear in the field of view from the corresponding images in the library to the face of the monitor screen. The four corners of a stored image are located by calculations in the face of the monitor screen to define a 4-sided polygon. The mapping of rows and columns of a stored image in the library to this polygon is done in two passes or stages. 
     The library input image rectangle has columns and rows with the same number of pixels as the columns and rows of the output image on the face of the cathode ray tube. The mapping of pixels from the input image to the output image involves a pixel magnifying and reducing process wherein pixels in the   input image are either larger or smaller than pixels in the output image. The input pixels are assembled in groups on a fractional basis so that each such group forms exactly one pixel in the output image.

The control facilitates precise temperature setpoint resolution. The gas sensors in the array have an improved construction density with reduction in size and an extended operating life provided by reduced power consumption. A programmable circuit functions as a programmable-­resistor temperature controller in a Wheatstone bridge configuration. A multiplying digital to analog converter circuit controls the ratio of voltage to current that functions as a resistance equivalent. The programmable circuit is interfaced with a computer to provide selectable temperature control for at least 256 setpoints.

Abstract: By enveloping a gas discharge lamp, such as a fluores­cent tube (2), in an outer glass tube (8), the discharge chamber of the fluorescent tube (2) is thermally insu­lated. This enables a sufficiently high temperature to be maintained in the fluorescent tube (2) for, e.g., mercury in the discharge chamber to be brought to a partial pressure at which good illuminating efficiency is obtained even at very low ambient temperatures around the lamp. The tubular envelope (8) is fixated at its ends to the fluorescent tube (2), in some suitable manner such as to surround the fluorescent tube and define a tubular space (10) of constant uniform width between the fluorescent tube and the surrounding en­velope. In order to provide a lamp which will ignite readily, the occurrence of space charges between the fluorescent tube (2) and the outer tube (8) has been eliminated, by the provision of siloxane seals (11) between the inner fluorescent tube and the tubular envelope, at the respective ends thereof.

Abstract: The method for intermediate amplification of digital signals with clock regeneration determines the phase difference between the reception timing signal and the local transmission timing signal and modifies the phase of the local transmission timing signal depending on the phase difference. It is particularly advantageous if the reception timing signal is used as the transmission timing signal as soon as the phase difference is essentially zero. It is possible as a result to minimise the start-up delay and also the packet spacing in that the number of bits which are to be temporarily stored can be kept down. Intermediate repeaters to carry out the method are indicated.
